Speclication of Letters Patent.

Patented July 13, 1915.

Application filed February 24, 1913. Serial No. 250,228.

citizen of the United States resident or" Cleveland, county of Cuyahoga, and State o?? Ohio, have invented a new and useful lui-- i prei/ement in Coke-Ovens, of whichthe following is a specification, the principle of the invention being herein explained and the best :node m which l have contemplated apu plying that principle, so as to distinguish from other inventions.

My invention relates to coke-ovens and. particularly to that type known as regenen" ative or regenerator-coke-ovens.

The object of the invention is to provide a coke-oven of the above speciiied character which will be economical and eiiicient in its operation.

Ehe said invention consists of means here ina-iter fully described and particularly set forth in the claims.

rihe annexed drawings and the following description set forth in detail certain means embodying my invention, the disclosed means, however, constituting but one of various mechanical forms in which the principle ofthe inventiony may be applied.`

ln said annexed drawings z-Figure l is a longitudinal vertical section of a coke-oven embodying my invention and taken upon a plane passing through the axis of one of the wiring-chambers. Fig. 9. is a transverse vertical section falten upon the plane indicated by line l-Il in Fig. l. Fig. 3 is a second transverse vertical section taken upon the plane indicatedby the line Ill-Hl in Fig. l. Fig. 4 is a vertical longitudinal section taken upon the plane indicated by line Fig. 5 is a Vhorizontal section taken' uponthe plane indicated by line V-V in Figs. l

The illustrated embpdimlent of my invention comprises the outer casing or structure A in which are formed a plurality of parallel coling-chambcrs A which extend from front to rear in the usual manner and are provided at its extremities with removable closures A2 and il, by means of which the contents thereof may bedischarged, as will lie understood by those skilled in the art. Charging openings a c: communicating with the too .of each colring-chamber are provided and 'closed means osuitable removable covers a. as shown in Fi` l.

y A`EXtendiing; from front to rear o the oven and respectively adjacent to4 the two side Walls of each coking-chamber, is a series of `combustion-chambers B B arranged in' pairs, the reference letters B B and B B representing respectively alternately occurring pairs of these chambers as shown .in Fig. 4. Vertical Walls a2 separate theadjacent pairs of chambers, and located intermediately of the two chambers of each pair isl a. vertical air-duct C. Openings a3 as in the walls a2, Figs. 3 and 4, afi'ord communication between adjacent chambersl of adjacent pairs, these openings being located at the bottom of the combustion-chambers as shown.

Beneath each ccking-chamber A and parallel therewith is the horizontal flue D and laterally of the series of combustionchambers are formed similar flues D D as shown in Fig. 2. `'It will therefore be observed that each series of combustion-chambers has two flues D or D' placed laterally with reference to its sides asis clearly shown in said Fig. 2. Each air-ductcommunicates by means of branches c e, with one of these hoiizo1ita.l\il1es D or D, such communication occurring alternately on the part' of the air-ducts between one seriesof combustionchambers, with flues on opposite sides of suchseries shown in Fig. 2. Taking one series of air-ducts from front to rear of the oven for an example, the first duct communicates'with the due on the right thereof, the second duct with the flue on the left thereof,

4the third duct'with the same lue on the directly with the rear of the regenerator bc' low it, the'neXt and adjacent flue communicates directly with the front of its regenerator, the next with .therear of its'regeneraator which is opposite theend which directly communicates with the ues D or D', is connected respectivel with passages F F', by means of ducts f as shown in Fig. 1.

. tor and so forth. That end of each regener- These passages F F', are placed beneath the regenerators, are lparallel with each other and extend transversely of the oven, and are so arranged that they may be connected either with a stack or with the atmosphere as may be desired. f

The up er end of each combustion-chamber B or B terminates some'distance-below thetop of the casing as shown in Fig. 4, and each such chamber communicates with an auxiliary chamber B2 by means of an opening I). Extending downwardly into the upper portion of each of these auxiliary chamers is a gas nozzle G. Lying horizontally upon opposite sides of the Vertical axial plane of each series of combustion-chambers andvin suitable depressions a4, Fi s. 2, 3 and 5, are the fuel-gas supply pipes H. All of the nozzles which discharge linto the auX- iliary chambers B2 above the combustionchambers B B, are connected to one of these pipes H, and all of the nozzles discharging into the chambers B2 B2 above the combustion-chambers B B are connected to the other of these pipes, and each such connection is controlled by meansof a suitable manually operable valve has shown in Figs.

3 and 4. The one end of one pipe H is connected with a header H and the opposite end of the other pipe is vconnected with a header H2. The passage of fuel-gas through these headers is controlled respectively by means of manually' operable valves h' h by means of which the supply of fuel-gas to all of the nozzles connected to all the pipes ll may be cut off simultaneously, while such fuelgas is permitted to How simultaneously to all of the nozzles connected-'to the other pipes H. In addition to this control it will bo noted that the flow from each nozzleA may also be regulated independently of the flow from all of the other nozzles by means of the valves h.

In order to effectually close the upper porl tion of the auxiliary chambers B2 B2 bricks a are fitted` therein and provided with a ertures from which the .nozzles exten as shown, and the cxtreme upper end of each of these chambers is closed by a suitable cover af. y

v The air-ducts C extend upwardly to the top of the casing as shown and their upper ends are closed by suitable covers a", Fig. 4. In the bottom of each such air-duct and opposite the branches c, is placed a slidable valve C usually in the form of a lirebrick,

by means of which the influx of air may be controlled. This valve is moved by means of a suitable rod inserted into the air-duct from the top after the cover a. has been removed, as will be understpod.

Aitor-ding communication between each combustion-chamber B or B', and the interi mediate air-duct C are two openings o o',

two of these openings communicating with each combustion-chamber'as shown in Fig. 3. These openings are located upon opposite sides of the vertical axial vplane, of the openings b through lwhich the fuelgas enters the top of the combustion-chamber.

The above described device o 'erstes as follows: Let it be assumedvthat t e F is connected with the stack and c e passage F is connected withthel atmosphere. The supply of fuel-gas is now turned ,o by means or" the corresponding valve L from header H2, and the gas permitted,'therefore, to pass into allthe pipes H. connected with these latter pipesv discharge gas into the pairs of combustion-chambers lissage- The nozzles B B, no such discharge taking place into the in communication with those regenerators which are connected with the passage F and atmospheric air is there-fore su lied to these combustion-chambersrB B. pon ignition of the gas and air, the mixture burns in the chambers B B and the gases"of.combuston pass out througgr theopenin4 as a into the adjacent com yustionLcham rs of the adjacent pairs B B these lattertherefore servin under these conditions, as pas' sages for t e gases of combustion. From thes'efpassages B therefore these ases of combustion pass into tlxeairducts which are located between the said chambers or passages B B and thence'into the correspending lues D. Fronrthe latter these hot gases pass into the regenerators connected with these fines, through. these regenerators and. thus out through the 'passage F and into the stack from whenoethey are discharged into the atmosphere.' In this manner alternate regenerators are heated b the After a given length of has elapsed the direction of travel of the gases is reversed. To effect this reversal, thev passage F is now connected with the atmosphere and the passage F with 'the stack,.gthgijnri;.

rangement vfor this purpose `(not--alx'iavn being of any well-known or acce design such asis familiar to those skill The fuel'gas is now shut o' from the bende H by means vof the valve associated in theartgr therewith, and 'turned into the headerHF;` i

by means of its valve 7a.. Such fuel-gas" is therefore su plied to those nozzles, which in ias the previous y described operationZ were 1in-' active. into the previously inactive combustionchambers which ywere serving as outlet-- Fuel-gas is therefore discharged l v coming air,

' lated by struction resides in i regenerators 4used for the discharge of ducts for the gasesloi combustion. Those air-ducts which were serving 'as outlets 1n the said previously described operation'jare and the ormerly inactive regenerators are The in# now being heated by the said gases.

however, passes through the regenerators which have been heated'in the former operation .by the gases o combustion, thus conserving heat as required.

After the lapse oi a second required pe# riod of time the operation is again reverse as will be readily understood. .Y

lThe influx of air intovthe regenerators from either oi" thepassages F orv F is regumeans of a sliding valve J, Fig. 1, usually in the form of a tire-brick which maybe reached and manipulated from the exterior through an aperture 'o8 provided 1ith a removable closure a". i

By means of the above described arrangeu ment of parts, l obtain a coke-oven which v,is economical andeiiicient in its operation.

particular advantage lembodied. 1n such' construct-ion lies in the arrangement of the 'fuel-gas supply pipes at the top of' the oven whereby each nozzle may be provided with a readily accessible valve so that the supply of fuel to each combustion-chamber, and therefore the combustion itself therein,may be regulated and controlled independently of every other combustion-chamber.

A further specific advantage of said conthe arrangement of the E, the ducts D and the passages F and F. Said ci the use of either the passage F or F', 'as the case may be, as an inlet for atmospheric air.; rlhese passages are also, as described, the gases of combustion after leaving the regenerators, and therefore absorb more or less of the residual' heat "from these gases ai'ter leavingftlie regenerators. When either of these passages is used as an air-inlet therefore, the atmospheric air is heated to some degree even before it enters the regenerators, an additional amount of heat which would otherwise be dissi-pa fr, ,eing thus conserved.

By arranging the combustion-chambers so that the air inlet discharges in the vicinity oi: the fuel-gas inlet, providing two airinlets to each combustion-chamber,

arrangement permits 4 and arranging these inlets laterally with respect Having fully described myy invention,

h what I' claim and desire to secure by Letters Patent is f l. ln a coke-oven, coking-chamber; a plurality of combustionchambers adjacent to one side-Wall of said neiging-chamber; a plurality of air-ducts, one such duct located between successively occurring pairs of combustion-chambers and commumcatingwith each member of such 'pairs at the'top thereof; adjacent chambers of adjacent pairs of such chambers communicating with each other at the bottom; and afuel-gasupply communicating With each combustion-chamber at the top.
